This is a new `feature` to allow setting a freshness threshold for servers
to catch up to before going healthy and serving queries.
- This will supercede the offset based checker if that is set
- This will wait until:
- your current offset is within 1 of the latest offset
- your latest ingested timestamp is non negative and within the desired
threshold
- will not work if you set a 0 or negative freshness
This still requires and respects the overall realtime "wait" variable so we
never get stuck forever.
This was tested in an internal QA cluster. We actually hit all cases:
- partitions with 0 offset with no messages were caught up
- partitions in error state waited the full time until going healthy
- partitions that were not fresh but then caught up
